Try to organise this better to make it clear which dependencies are
ours, and which we've gotten just because Xvnc is based on xorg-server.

Also update the dependency list to the current state of things.

This is what upstream does, so let's add it in case some dependency is
added implicitly by the Debian build tools somewhere.

This is done for us, so stop having explicit lists that we forget to
update properly.

Follow the format upstream Debian/Ubuntu uses.

It is generally pulled in as a requirement from GnuTLS, but let's be
explicitly now that we make use of nettle directly.

Linux implementation using ffmpeg

This version of Ubuntu is no longer fully supported so let's stop caring
about builds there.

This was removed from Ubunut's X.org packages years ago, so drop it from
our packing as well.

This makes our builds directly compatible with most distributions
without packagers/users having to specify extra flags.

This sets up a more correct session as there are key tasks that
need to be performed by PAM. E.g. systemd will allocate cgroups
and start base services.

In order to easily handle this as a system service the mapping of
displays is now done via a configuration file.

It is the most common init system these days so it should not be
hidden in the contrib/ directory.

This also removes all old SysV files from the contrib packages.

Install some example files to make things more easily discoverable.

Make the builds faster as we now run them often via Travis.

The supporting scripts weren't really up to date, so remove them
and just require the packager to include FLTK in the source
tarball.

It is needed by x0vncserver.

It is needed to build Xvnc.

Packages for RHEL 5 and Ubuntu 12.04 are no longer maintained, so
remove those files.

Our main web site now supports https, so update all references.

Debian patches libtool so that the default value of
link_all_deplibs is set to 'no' rather than 'unknown',
causing transitive dependencies in shared objects to
be lost.

The package is based on the contrib ubuntu-trusty debian package. The
following modifications have been made:

The current tigervnc sources can be used unmodified as the .orig
tarball for the debian package, so get-orig-source.sh is gone.

The ubuntu xorg-server-sources package provides the xorg sources used
to build tigervnc. The two small patches which where in the trusty
quilt series are now applied to the xorg sources after they have been
extracted. There is no quilt series anymore at this point.

Fltk 1.3.3 is available in the xenial repositories and it is used to build
xtigervncviewer. No need to get the fltk sources. patch_fltk.sh is gone.

Fixed some dependencies to reflect changes between trusty and xenial.

Removed configure options not recognized by configure.

The install target is not called a second time for the viewer package,
but the viewer files are moved from the server installation. (Eliminate
file conflicts during binary package installation.)

Note: Some dependencies (including libfltk1.3 and xorg-server-source) are
found in the xenial universe repository only.

These files are not Red Hat or Ubuntu specific, so install them
on all Unix systems where the viewer is installed.

This workaround is no longer needed as we've fixed the bad interaction
with libtool.

el5 and el6 need newer versions of gnutls (and it's prereqs) than are available natively.
